[Relationships between immissions of plumb and zinc and the levels of plumb, zinc and cadmium in blood, urine and hair in children (author's transl)].

In children from an industrial area with a high degree of lead, zinc and cadmium pollution, the lead levels in blood and hair increased with increasing lead fall-out, and the cadmium concentration in the urine increased with increasing zinc fall-out. Children from the center of town presented significantly higher lead values in the blood and hair samples and, significantly lower urine lead concentration than those children investigated, living in the peripheral districts of the industrial town. The lead content of blood and hair samples corresponded to the various lead immission levels encountered. The results give rise to the supposition that biological cadmium interactions are influenced by simultaneous lead uptake.
